This entry represents the Ariadne domain found in the Ariadne subfamily E3 ubiquitin ligase proteins [4]. The C-terminal Ariadne domain adopts an elongated four-helix bundle consisting of an antiparallel arrangement of seven-to-ten-turn long helices. The Ariadne domain is straddled on one side by the IBR domain, and on the other by the RING2 domain. Notably, the Ariadne domain embraces the surface of RING2 containing the catalytic Cys357 [1]. The ariadne Domain Masks the HHARI Catalytic Cys357 and Inhibits Intrinsic E3 Activity [1].
The C3HC4 type zinc-finger (RING finger) is a cysteine-rich domain of 40 to 60 residues that coordinates two zinc ions, and has the consensus sequence: C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-C-X2-C-X(4-48)-C-X2-C where X is any amino acid [1]. Many protein ...
The C3HC4 type zinc-finger (RING finger) is a cysteine-rich domain of 40 to 60 residues that coordinates two zinc ions, and has the consensus sequence: C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-C-X2-C-X(4-48)-C-X2-C where X is any amino acid [1]. Many proteins containing a RING finger play a key role in the ubiquitination pathway [2].

This ubiquitin-associated (UBA) domain is found at the N-terminal end of human E3 ubiquitin-protein ligase ARIH2 and similar proteins mainly found in animals. ARIH2 catalyses ubiquitination of target proteins together with ubiquitin -conjugating enzyme E2 UBE2L3. It acts as an atypical E3 ubiquitin-protein ligase by working together with cullin-5-RING ubiquitin ligase complex [2-5,10].
The IBR (In Between Ring fingers) domain is often found to occur between pairs of ring fingers (Pfam:PF00097). This domain has also been called the C6HC domain and DRIL (for double RING finger linked) domain [2]. Proteins that contain two Ring fing ...
The IBR (In Between Ring fingers) domain is often found to occur between pairs of ring fingers (Pfam:PF00097). This domain has also been called the C6HC domain and DRIL (for double RING finger linked) domain [2]. Proteins that contain two Ring fingers and an IBR domain (these proteins are also termed RBR family proteins) are thought to exist in all eukaryotic organisms. RBR family members play roles in protein quality control and can indirectly regulate transcription [3]. Evidence suggests that RBR proteins are often parts of cullin-containing ubiquitin ligase complexes. The ubiquitin ligase Parkin is an RBR family protein whose mutations are involved in forms of familial Parkinson's disease [3][4].
